This document gives guidelines for assessing the overall performance of a quantitative descriptive
panel and the performance of each panel member.
This document is applicable to the validation of the training of individual assessors or panels, as well as
to the performance monitoring of established panels.
This document does not apply to the panel performance for descriptive methods where the individual
scores of each assessor are not recorded, where there is no single list of attributes that is common to all
the assessors, or where dominance rather than intensity is measured. Consequently, the performance
of descriptive panels using methods such as consensus profile, free-choice profile, flash profile and
temporal dominance of sensations (TDS) are out of scope.
The methods specified in this document are for monitoring and assessing the ability of a panel and its
assessors to discriminate between products, the agreement between assessors of the same panel and
the repeatability of these assessors in their intensity scoring.
Reproducibility, including both the comparison between panels and the comparison within the same
panel of several evaluations conducted under different conditions (i.e. separated in time), is out of scope
of this document.
The methods specified in this document can be used, in full or a selection only, by the panel leader to
appraise continuously the performance of panels or individual assessors. The methods listed are not
exhaustive and other appropriate methods can also be used.

This document specifies a procedure for the detection of a DNA sequence present in a genetically modified linseed (Linum usitatissimum) line (event FP967, also named as “CDC Triffid”). For this purpose, extracted DNA is used in a real-time PCR and the genetic modification (GM) is specifically detected by amplification of a 105 bp DNA sequence representing the transition between the nopaline synthase gene terminator (Tnos) from Agrobacterium tumefaciens and the dihydrofolate reductase gene (dfrA1) from a Class 1 integron of Escherichia coli. The method described is applicable for the analysis of DNA extracted from foodstuffs. It can also be suitable for the analysis of DNA extracted from other products such as feedstuffs and seeds. The application of this method requires the extraction of an adequate amount of amplifiable DNA from the relevant matrix for the purpose of analysis.

This part of ISO 23036 specifies a method that is applicable for the detection of Anisakidae L3 larvae commonly found in marine and anadromous fishes. The method can be applied to fresh fish and/or frozen fish, lightly processed fish products, such as marinated, salted or smoked, and it’s also suitable for visceral organs as confirmatory method for visual inspection scheme.
The artificial digestion method allows quantifying parasitic infections by estimating the number of parasites in the fish musculature and, when applied to fresh fish or lightly processed fish products (never frozen before processing), determining the viability of Anisakidae L3, which may be present.
This method doesn’t allow determining species or genotype of detected parasites, which identification is made by morphological and/or molecular methods.

This document specifies a method for the semi-quantitative analysis of oils, fats and oil/fat-related samples (deodistillates). It is applicable to the screening of oils, fats and oil/fat-related samples to obtain main (e.g. triglycerides) and minor (e.g. sterols, sterol esters, tocopherols, wax esters, fatty alcohols, glycerol) component information in one single analysis. For a truly quantitative analysis of pre-identified compound classes, specific methods are more appropriate. The method can also be used as a useful qualitative screening tool for the relative comparison of sample compositions.

This document specifies two methods for the determination of the melting point in open capillary tubes, commonly known as the slip melting point, of animal and vegetable fats and oils (referred to as fats hereinafter). —   Method A is only applicable to animal and vegetable fats which are solid at ambient temperature and which do not exhibit pronounced polymorphism. —   Method B is applicable to all animal and vegetable fats which are solid at ambient temperature and is the method to be used for fats whose polymorphic behaviour is unknown. For the determination of the slip melting point of palm oil samples the method given in Annex A shall be used. NOTE 1  If applied to fats with pronounced polymorphism, method A will give different and less satisfactory results than method B. NOTE 2  Fats which exhibit pronounced polymorphism are principally cocoa butter and fats containing appreciable quantities of 2-unsaturated, 1,3-saturated triacylglycerols.

This document specifies a procedure for determining whether a perceptible sensory difference or
similarity exists between samples of two products. The method is a forced-choice procedure. The
method is applicable whether a difference exists in a single sensory attribute or in several attributes.
The method is statistically more efficient than the duo-trio test (described in ISO 10399), but has
limited use with products that exhibit strong carryover and/or lingering flavours.
The method is applicable even when the nature of the difference is unknown [i.e. it determines neither
the size nor the direction of difference between samples, nor is there any indication of the attribute(s)
responsible for the difference]. The method is applicable only if the products are homogeneous.
The method is effective for:
a) determining that:
1) either a perceptible difference results (triangle testing for difference);
2) a perceptible difference does not result (triangle testing for similarity),
when, for example, a change is made in ingredients, processing, packaging, handling or storage;
b) selecting, training and monitoring assessors.
